Damn, this is a good idea...I was just thinking how much cooler 7sage would be if they had campus reps (unpaid, who like interned for them)...it would be easier to get people together and so on..
Certainly not during 1L. However, I do intend to work during both 2L and 3L. I interned with a ton of law students who mentioned that they were required to intern or work during 2L. Most of whom ended up wanting to work during 3L.
Plenty of us here have done exactly what you're planning. A buddy of mine took the LSAT last fall, was accepted to his top school, then delayed further to intern.
Taking another year or two off should be fine.
